Issue Description:

In Polish language this example have one minor grammar mistake:

let dateFormatter = DateFormatter()
dateFormatter.setLocalizedDateFormatFromTemplate("MMMMy")
let date = dateFormatter.string(from: Date())
 
print(date)

date variable outputs "styczeń 2019" (on 6th of January 2019) when it should capitalize first letter of month (as in "Styczeń 2019"). I couldn't find any format template that capitalizes it and i had to do it manually (by creating an extension to String). It is not critical or anything, but it's definitely not correct.
